as we had to cut a large hole in the trees to see it. We saw a Western Warbler and a flock of Band-tailed Pigeons but did not get any. Resizing shot two Townsend's and a Margilliray's Warbler around the camps while we were away. May & Will and I walked up the canon, leaving the others in camp. We shot eight Townsend's Warblers, seven of which were females, and the eight a male in plumage almost identical with the female. This would seem to indicate that the males do not get their full plumage on the spring following the year in which they were hatched, especially as we have shot several males in this plumage. The first week we were here all the Townsend's Warblers we saw were males. Now they are about all females. I do not know if this applies to the Western Warblers as well, as they have been much more rare all through. We also shot a Grace's Warbler and a female White-throated Swift. From the hairy of the Swift, they are evidently not laying yet. While we were gone Howard shot a Flammulated Screech Owl and said that he saw two more. Birds are coming in here very fast. There are lots of Cassin's, Plumbrous and Warbling Vireos, Hepatic and Louisiana Tanagers, Blake- Headed Grosbeaks, and Western House Wrens around, while a few days ago there were hardly any, or none, to be seen. Saw a Golden Eagle, and a few Band-tailed Pigeons, and two Western Warblers.
